DETAILED DESCRIPTION

[0043] Referring to FIGS. 1A and 1B, a chair 100 and an ottoman 200
according to aspects of the present invention are illustrated. The chair
100 includes a seat 102, right and left armrests 104a,b, a seatback 106,
and right and left base structures 110a,b. The ottoman 200 includes a top
structure 202, a body 204, and right and left base structures 206a,b. In
FIG. 1A, the ottoman 200 is positioned relative to the chair 100 so that
a person can use the top structure 202 as a footrest while seated in the
chair 100. In FIG. 1B, the ottoman 200 is stored in a recess 108 under
the seat 102 of the chair 100, when the ottoman 200 is not required for
leg support. The chair 100 is structurally configured to provide the
features of a glider rocker while accommodating storage of the ottoman
200 in the recess 108.

[0044] Referring to FIG. 2, structural features of the chair 100 are
illustrated. The chair 100 includes two base structures 110a,b on right
and left sides of the chair 100, respectively. The base structures 110a,b
allow the chair 100 to be stably positioned on a floor surface and
support an assembly 111 of the chair 100. The assembly 111 includes a
seat support 112, right and left armrest supports 114a,b, and a seatback
support 116. The seat support 112, armrest supports 114a,b, and seatback
support 116 provide the internal structures (no cushion, upholstery,
covering, etc.) for the seat 102, armrest 104a,b, and the seatback 106,
respectively. The internal structures and other aspects of the chair 100
as well as the ottoman 200 may be formed from any combination of wood,
metal, plastic, composite material, or any other material having
appropriate structural characteristics, e.g., strength, hardness,
durability, etc. Cushions, upholstery, coverings, and the like may be
applied to the internal structures according to any technique. The
structures of the chair 100 as well as the ottoman 200 may be assembled
according to any combination of fastening techniques, including, but not
limited to, the use of screws, nails, pegs, rods, rivets, bolts,
supporting brackets and plates, interlocking elements, press-fit
connections, adhesives, and the like.

[0045] The seat support 112, armrest supports 114a,b, and seatback support
116 are assembled in a fixed configuration and move together in
gliding/rocking motion relative to the base structures 110a,b. Although
the seat support 112, armrest supports 114a,b, and seatback support 116
may move together relative to the base structures 110a,b, it is
contemplated that the configuration of the seat support 112, armrest
supports 114a,b, and seatback support 116 relative to each other may be
adjusted and releasably fixed. For example, the seatback 106 may be
adjusted relative to the seat 102 and the armrest supports 114a,b for
custom comfort.

[0046] As shown in FIG. 2, the base structures 110a,b are transversely
coupled by a cross-brace 110c for additional stability. The cross-brace
110c is positioned so that sufficient space is provided for the recess
108 and the ottoman 200 can be stored in the recess 108. In alternative
embodiments, the cross-brace 110c is not employed and the base structures
110a,b provide sufficient stability for chair 100.

[0047] A user can use his/her body to move the chair 100 forward and
backward in a gliding/rocking mode. To permit relative movement between
the base structures 110a,b and the frame assembly 111, the seat support
112 is coupled to the base structures 110a,b by a respective linkage
system 120a,b. The linkage systems 120a,b allow the frame assembly 111 to
swing back and forth so that the chair 100 can provide a smooth
gliding/rocking motion. The linkage systems 120a,b are disposed in
cavities 115a,b formed in each respective armrest 104a,b of the chair
100. It is noted that the armrest supports 114a,b are not directly
coupled to the base structures 110a,b, so that the seat support 112, the
armrest supports 114a,b, and the seatback support 116 can move in fixed
configuration relative to the base structures 110a,b. The cavities 115a,b
formed by the armrests 104a,b accommodate the linkage systems 120a,b
while also allowing the armrests 120a,b to move with the seat 102 and
seatback 106 relative to the base structures 110a,b. By locating the
linkage systems 120a,b in the cavities 115a,b, a space under the seat 102
is open to provide the recess 108 for receiving the ottoman 200. In
addition, keeping the linkage systems 120a,b hidden within the armrests
104a,b minimizes any risk of injury from contact with their moving parts.

[0048]FIG. 3 illustrates selected structural features of the chair 100
more clearly by omitting some aspects of the frame assembly 111. As shown
in FIG. 3, the linkage systems 120a,b include side walls 121a,b that are
coupled to, and extend upwardly from, the respective base structures
110a,b. Upper bars 122a,b are disposed across respective side walls
121a,b. Referring to the right linkage system 120a shown more clearly in
FIG. 3, a front linkage arm 123a and a rear linkage arm 124a are
pivotally coupled to the upper bar 122a and extend downwardly to be
pivotally coupled to a seat bracket 130 coupled to the seat support 112.
The linkage arms 123a and 124a are non-parallel and improve the quality
of motion of the frame assembly 111 by making the motion more linear. The
left linkage system 120b is configured in a manner similar to the right
linkage system 120a.

[0049] The seat bracket 130 coupled to the seat support 112 is shown
further in FIG. 4. The bracket 130 includes two transverse bars 131a,b
that extend along the bottom of the seat support 112. The two transverse
bars 131a,b extend downwardly from each side of the seat support 112 and
are coupled to a right lower bar 132a and a left lower bar 132b. The
right lower bar 132a is pivotably coupled to the linkage arms 123a and
124a of the right linkage system 120a. Correspondingly, the left lower
bar 132b is pivotably coupled to the linkage arms 123b and 124b of the
left linkage system 120b.

[0050] In addition to providing a rocking motion, movement of the frame
assembly 111 relative to the base structures 110a,b also provides various
seating positions. As illustrated in FIG. 5A, the chair 100 provides a
recline mode. During operation, when the user pushes rearwardly against
the seatback 106, the seat 102 and seat bracket 130 move correspondingly
with the seatback 130. The linkage arms 123a,b and 124a,b pivot with the
movement of the seat bracket 130, which is coupled to the linkage arms
123a,b and 124a,b. As the linkage arms 123a,b and 124a,b pivot, the rear
linkage arms 123a,b effectively push the rear of the seat bracket 130
downwardly. Meanwhile, the front linkage arms 123a,b effectively pull up
the front of the seat bracket 130. The combined action of the
non-parallel linkage arms 123a,b and 124a,b cause the frame assembly 111
to tilt rearwardly and move into the recline position. The user achieves
the recline position simply by shifting his/her weight to the rear
without employing a supplemental recline mechanism.

[0051] As further illustrated in FIG. 5A, a magnetic locking system is
employed to keep the chair 100 in the recline position. In the magnetic
locking system, magnetic elements 142a,b are attached to respective front
linkage arms 123a,b, and magnetic elements 144a,b are attached to the
seat bracket 130. The magnetic elements as described herein may include a
combination of magnets (of opposing polarity) or a combination of magnets
and materials, e.g., iron, that are attracted to magnets. The magnetic
elements 142a,b and 144a,b are located so that when the front linkage
arms 123a,b pivot into the recline position, corresponding magnetic
elements 142a,b and 144a,b engage each other. The attraction between the
corresponding magnetic elements 142a,b and 144a,b lock the chair 100 into
the recline position by keeping the front linkage arms 123a,b in a
releasably fixed position relative to the bracket 130 and thus, the frame
assembly 111. The frame assembly 111 can move relative to the base
structures 110a,b only if the linkage arms 123a,b and 124a,b are allowed
to pivot relative to the bracket 130. To exit from the recline position,
the user shifts his/her weight forward and acts sufficiently against the
attraction between the magnetic elements 142a,b and 144a,b, causing the
linkage arms 123a,b and 124a,b to pivot in the reverse direction.

[0052] In some embodiments, as generally shown in the simplified diagram
of FIG. 5B, the chair 100 also provides an ingress/egress position that
releasably locks the chair 100 into a position that allows a user to
enter and exit the chair 100 more easily. When the user shifts his/her
weight forward, the seat bracket 130 moves forward with the seat 102, and
the linkage arms 123a,b and 124a,b pivot with the movement of the seat
bracket 130. As the linkage arms 123a,b and 124a,b pivot in this case,
the rear linkage arms 123a,b effectively lift the rear of the seat
bracket 130 upwardly. Meanwhile, the front linkage arms 123a,b
effectively push down the front of the seat bracket 130. The combined
action of the non-parallel linkage arms 123a,b and 124a,b cause the front
of the frame assembly 111 to tilt downwardly. The resulting angle allows
the user to enter or exit the chair 100 more easily. The user achieves
the ingress/egress position simply by shifting his/her weight forward
without employing a supplemental mechanism. A lock system similar to the
magnetic locking system described above may be employed to lock the chair
100 into the ingress/egress position.

[0053] Alternative mechanisms may be employed to lock the chair 100 into
various positions. For example, some embodiments may employ a latch that
releasably locks one or more of the linkage arms 123a,b relative to the
frame assembly 111. The latch may be released by an easily accessible
release handle. In another example, one or more of the linkage arms
123a,b may include a locking pin that moves in a slot along a locking arm
and when the seat reaches the desired position, a spring-loaded nut of
the locking pin locks into a locking ring positioned along the slot. The
locking pin is released when a cable attached to the locking arm is
pulled by a release handle and allows the spring to be compressed and the
nut of the locking pin to move from the locking ring. It is also noted
that when the ottoman 200 is positioned in the recess 108 of the chair
100 as shown in FIG. 1B, the ottoman 200 may block any motion of the
frame assembly 111 relative to the base structures 110a,b, thereby
blocking the chair from any gliding/rocking motion.

[0054] The chair 100 described previous is an example embodiment
illustrating various aspects of the present invention. It is contemplated
that the chair 100 may include additional and/or alternative features.
For example, as shown in FIGS. 21A and B, the chair 100 is equipped with
various optional features located on various parts of the chair 100. In
particular, the armrest 104a includes a flip-out desk and lamp system 150
as well as a cup holder 151. The armrest 104b includes a docking station
152 for receiving a portable audio device, and correspondingly, a
plurality of speakers 153 are disposed in different locations of the
chair 100 to provide an integrated audio system. Furthermore, the
seatback 106 includes a heated back massager 154. In addition, the base
structures 110a,b include light sources 155, e.g., LED's approximately 2
inches above the floor surface, to provide path lighting in front of the
chair 100. The path lighting is advantageous when the user is attending
to a child in a dark room, e.g., in the middle of the night. The path
lighting, for example, helps the user move through a dark room or operate
an ottoman positioned in front of the chair 100. In some embodiments, the
light sources 155 may include a cluster of red, green, blue (RGB) LED's
that can provide color changing effects, e.g., according to a relaxing
pattern. The armrest 104b also includes a control panel 156 for
controlling features, such as the volume to the speakers 153, the
massager 154, or the light sources 155. The electrically powered features
may draw power from batteries and/or a conventional electrical outlet.

[0055] In some embodiments, the light sources 155 are manually activated,
e.g., via the control panel 156. Additionally or alternatively, control
of the light sources 155 may be automated. For example, the light sources
155 may be turned on/off or dimmed/brightened in response to a timing
system and/or a sensor system (e.g., pressure sensors, magnetic sensors,
light sensors, etc.). In one embodiment, the user may turn the light
sources 155 on manually by operating an ON/OFF switch, and in response,
the light sources 155 provide lighting for a predetermined amount of
time, e.g., 2 minutes, until a timing system turns the light sources off.

[0056] FIGS. 22A and B illustrate another embodiment for controlling the
light sources 155. As FIG. 22A illustrates, the chair 100 also includes
an ON/OFF switch 157 which may be provided on the control panel 156, a
control device 160, at least one magnetic sensor 161, and at least one
pressure sensor 162. The control device 160 includes modules for
controlling the light sources 155, e.g., primary and secondary timers.
The control device 160 may also include a battery for providing power to
the light sources 155. As FIG. 22B illustrates, when the user comes into
contact with the chair 100, a magnetic sensor 161 disposed on the chair,
e.g., at the linkage system 120b, detects motion by the chair 100. If the
room is sufficiently dark, a primary timer activates the light sources
155 for a first predetermined amount of time, e.g., 30 seconds. In some
cases, other features such as the audio system may be also activated. The
light sources 155 may slowly brighten until fully illuminated and/or may
provide color changing effects with RGB LED' s during the first
predetermined amount of time. The primary timer deactivates the light
sources 155 after the first predetermined amount of time. The user may
manually control the light sources 155 so that they remain illuminated
for a desired period after the first predetermined amount of time. A
pressure sensor 162 disposed on the seat support 112 senses the user
sitting in the chair 100. Once the user gets up from the chair 100, a
secondary timer activates the light sources 155 (if not already active)
for a second predetermined amount of time, e.g., 2 minutes. After the
second predetermined amount of time, the light sources 155 deactivate.

[0057] As described previously, cushions, upholstery, coverings, and the
like may be applied to the internal structures according to any
technique. The chair 100 may be outfitted in an unlimited variety of
upholstery configurations. The upholstery may be removable slip covers to
facilitate cleaning and/or to provide changeable designs. In some
embodiments, the chair 100 is not completely upholstered and may be a
hybrid wood and upholstered chair. The chair 100 may also include a
variety of cushions, such as a seat cushion or elbow pads. The height,
width, and position of the cushions may vary. Furthermore, the cushions,
such as elbow pads, may be removed according to user preference. Indeed,
it is contemplated that the chair 100 may be shipped as any combination
of sub-assemblies or modules that require final assembly by the consumer,
including the application of separate cushions, upholstery, coverings,
and the like.

[0058] Referring to FIGS. 6-11, structural features of the ottoman 200 are
illustrated. The ottoman 200 provides two operating modes: a gliding mode
and a nursing mode. FIG. 6 illustrates the ottoman 200 in the gliding
mode. In the gliding mode, the top structure 202 and the body 204 move
together relative to base structures 206a,b in a backward and forward
direction. When used with the chair 100, the ottoman 200 provides a
greater range of gliding movement for the user. The body 204 is coupled
to the base structures 206a,b with linkage systems 210a,b on each side.
FIG. 8 illustrates aspects of the right base structure 206a and the right
linkage system 210a, which are disposed in a cavity 205a defined by the
body 204. The right linkage system 210a includes a side wall 213a that
extends upwardly from base structure 206a which is positioned on a floor
surface. The linkage system 210a includes an upper bar 211a that is
positioned along the top of the side wall 213a. A pair of non-parallel
linkage arms 213a and 214a are pivotally coupled to the upper bar 211a
and extend downwardly where they are pivotally coupled to a wall 216a of
the body 204. The left linkage system 210b on the opposite side of the
ottoman 200 is configured in a manner similar to the right linkage system
210a. In the gliding mode, the linkage arms 212a,b and 214a,b swing to
allow the body 204 (and the top structure 202) to glide relative to the
base structures 206a,b. The top surface 202a of the top structure 202
provides a substantially horizontal footrest.

[0059] FIG. 7 illustrates the ottoman 200 in the nursing mode. In the
nursing mode, the top structure 202 is moved relative to the body 204 to
provide an angled footrest. Advantageously, the angled footrest provides
more comfortable and stable support for a user who is holding or nursing
an infant while seated in the chair 100. It is understood, however, that
the ottoman 200 may have more general uses when it is in the nursing
mode. FIG. 9 illustrates an example technique for configuring the ottoman
200 from the gliding mode shown in FIG. 6 to the nursing mode shown in
FIG. 7. In step A, the user, e.g., with a foot, pushes upward against a
bottom surface 202b of the top structure 202 at a first end 202c. The
first end 202c of the top structure 202 includes an indentation 221 on
the bottom surface 202b to help the user engage the bottom surface 202b
with his/her foot.

[0060] FIGS. 8-10 collectively illustrate a guide system that guides
movement of the top structure 202 relative to the body 204, from the
gliding mode to the nursing mode. In particular, the top structure 202
includes pins 222a,b on respective sides of the top structure 202,
proximate to the first end 202c. The pins 222a,b extend respectively from
the top structure 202 into curved tracks 223a,b disposed in the body 204.
The top structure 202 also includes pins 224a,b on respective sides of
the top structure 202, proximate to a second end 202d. The pins 224a,b
extend respectively from the top structure 202 into straighter tracks
225a,b disposed in the body 204. The curved tracks 223a,b guide movement
of corresponding pins 222a,b proximate to the first end 202c, and the
straighter tracks 225a,b guide movement of corresponding pins 224a,b
proximate to the second end 202d.

[0061] Generally, the combined movement of the pins 222a,b and 224a,b
along the tracks 223a,b and 225a,b causes the top structure 202 to move
into an angled position relative to the body 204. Pushing upward on the
first end 202b of the top structure 202 in step A causes the top
structure 202 to pivot upward about the pins 224a,b proximate to the
second end 202d. The pins 222a,b proximate to the first end 202c move
upwardly along the corresponding curved tracks 223a,b.

[0062] In step B, the user pulls the top structure 202 back, as shown in
FIG. 9. Pulling back on the top structure 202 causes the top structure
202 to move horizontally. The pins 222a,b move back along the
corresponding curved tracks 223a,b, and the pins 224a,b move back along
the corresponding straight tracks 225a,b until the straight tracks 225a,b
end and the pins 224a,b can no longer move. At this point, the top
structure 202 pivots about the pins 224a,b and the pins 222a,b move
downward along the corresponding curved tracks 223a,b.

[0063] In step C, the user allows the first end 202c to lower until the
pins 222a,b reach the bottom of the corresponding curved tracks 223a,b.
Here, the pins 222a,b proximate to the first end 202c are positioned a
distance below the pins 224a,b proximate to the second end 202d and thus
the top structure 202 extending between the pins 222a,b and 224a,b is
angled relative to the horizontal.

[0064] As shown in FIG. 10, during the nursing mode, the top structure 202
is in contact with a linkage arm stabilizer bar 226 that extends
transversely between the linkage arms 212a,b. The top structure 202
prevents any movement by stabilizer bar 226 and thus the linkage arms
212a,b. As such, there is no gliding motion by the ottoman 200 when it is
in the nursing mode. Alternatively, one or more of the pins 222a,b
proximate to the first end 202c may be moved directly against one of the
linkage arms 212a,b so that the linkage arms 212a,b and 214a,b cannot
swing.

[0065]FIG. 11 illustrates another ottoman 300 which may be employed, for
example, with the chair 100. The ottoman 300 includes a top structure 302
and a body 304. The top structure 302 moves relative to the base 304 to
provide two operating modes: a gliding mode and a nursing mode. The top
structure 302 is coupled to the base 304 with linkage systems 310a,b on
respective sides of the ottoman 300. As shown in FIG. 11, each linkage
system 310a,b includes a respective pair of non-parallel linkage arms
312a,b and 314a,b that are pivotally coupled to each of the top structure
302 and the base 304. In the gliding mode, the linkage arms 312a,b and
314a,b of the linkage systems 310a,b swing to allow the top structure 302
to glide horizontally relative to the base 304.

[0066] To configure the ottoman 300 from the gliding mode to the nursing
mode, the user, e.g., with a foot, pushes against the top structure 302
until a magnetic element 322 on one of the linkage arms, e.g., linkage
arm 314b, moves into contact with a corresponding magnetic element 324 on
the base 304. A magnetic locking system for the ottoman 300 includes one
or more magnetic elements 322 disposed on the top structure 302 and one
or more magnetic elements 324 disposed on the base 304. The magnetic
elements 322 and 324 attractively engage each other to lock the top
structure 302 against the base 304 to prevent relative motion between the
top structure 302 and the base 304. With the top structure 302 locked
into place by the magnetic locking system 320, an angled footrest 326
fixed to the base 304 below the top structure 302 is uncovered. The
angled footrest 326 provides the nursing mode. The top structure 302 can
be released from the base 304 by applying a force to the top structure
302 to overcome the magnetic locking system and return the ottoman 300 to
the first operating mode.

[0067]FIG. 12 illustrates yet another ottoman 400 which may be employed,
for example, with the chair 100. The ottoman 400 includes a top structure
402 and a base 404. Like the ottoman 300, the top structure 402 moves
relative to the base 404 to provide two operating modes: a gliding mode
and a nursing mode. The top structure 402 is coupled to the base 404 with
a linkage system 410 on each side. Each linkage system 410 is configured
in a manner similar to the linkage systems 310a,b described above. In
particular, each linkage system 410 includes a pair of non-parallel
linkage arms that are pivotally coupled to each of the top structure 402
and the base 404. In the gliding mode, the linkage arms of each linkage
system 410 swing to allow the top structure 402 to glide horizontally
relative to the base 404.

[0068] To achieve the nursing mode, the user (e.g., with a foot) pushes
against the top structure 402 until an angled footrest 426 fixed to the
base 404 is uncovered. The top structure 402 is sized so that the angled
footrest 426 is uncovered by allowing the top structure 402 to glide to
one side without locking the top structure 402 into place, e.g., without
the magnetic locking system 320 described above. A larger top structure
402 would otherwise require a locking mechanism to move the top structure
402 completely out of the way against the linkage systems 410.

[0069] The ottoman 400 also includes a storage drawer 430. As shown in
FIG. 12, the storage drawer 430 may slide through a passageway that
extends through the body 404, so that the storage drawer 430 is
accessible from two opposing sides of the ottoman 400.

[0070] Referring to FIG. 13, another ottoman 500 is illustrated. Although
the ottoman 500 may be similar to the other embodiments described
previously, the ottoman 500 also includes a heel arch 540. The heel arch
540 is an indentation along the top surface 502a of the top structure 502
that allows a user seated in the chair 100 to engage and position the
ottoman 500 with his/her feet. In particular, the person can move the
ottoman into or out of the recess 108 under the chair 100. The chair 100
may optionally include a handle 550, as shown in FIG. 13, which operates
a cantilever bar 552 which pushes the ottoman 500 a sufficient distance
outward to allow the user to engage the ottoman 500 using the heel arch
540.

[0071] Referring to FIGS. 14A-C, yet another ottoman 600 is illustrated.
The ottoman 600 includes a top structure 602 and a base 604. The top
structure 602 moves relative to the base 404 to provide a gliding mode.
The top structure 602 is coupled to the base 604 with a linkage system
610 on each side. Each linkage system 610 is configured in a manner
similar to the linkage systems described above. In particular, each
linkage system 610 includes a pair of non-parallel linkage arms that are
pivotally coupled to each of the top structure 602 and the base 604. In
the gliding mode, the linkage arms of each linkage system 610 swing to
allow the top structure 602 to glide horizontally relative to the base
604.

[0072] The top structure 602 of the ottoman 600 acts as a removable lid
that opens to an interior storage area 630. As shown in FIG. 14c, the top
structure 602 can be stably positioned on the floor surface and against
the base 604 to provide an angled, e.g., approximately 45-degree, surface
that provides a nursing mode for the ottoman 600. A bracket 620 may be
employed to position the top structure 602 stably against the base 604.
The cut-away view of FIG. 14c illustrates an embodiment of the bracket
620, which is coupled to the bottom surface of the top structure 602 and
engages a wall of the base 604 to position the top structure 602 at a
particular angle. The bracket 620 prevents the top structure 602 from
sliding down the side of the base 604.

[0073] FIGS. 15-20 illustrate features of another ottoman 700 that may be
employed, for example, with the chair 100. FIG. 15A illustrates the
ottoman 700 in gliding mode, while FIG. 15B illustrates the ottoman 700
in nursing mode. As shown in FIG. 16, the ottoman 700 has a central
support structure 710, linkage systems 720, and a top structure 730. The
top structure 730 and the central support structure 710 are pivotably
coupled to the linkage systems 720 via pivoting hardware.

[0074] In the gliding mode, the linkage systems 720 allow the top
structure 730 to move relative to the central support structure 710,
i.e., move substantially laterally in directions A or B as shown in FIG.
16. As further illustrated in FIGS. 16 and 17, the top structure 730
includes a top platform 731, top supports 732, side bars 733, and bottom
supports 734. The top platform 731 may be a padded platform. The padded
platform, for example, may be wood covered with padding and a leather,
fabric, or synthetic cover. The top platform 731, for example, may have a
platform area of about 20 inches by about 16 inches. Of course, the
dimensions of the ottomans described herein and their structural elements
may vary depending on a number of factors, for example, size of the user,
market preferences, and/or dimensions of the corresponding chair, e.g.,
the chair 100.

[0075] The top supports 732 may be elongated structural supports rigidly
coupled to the top platform 731. For example, the top supports 732 may be
wooden bars having a rectangular cross-section of similar or slightly
shorter length than the corresponding dimension of the top platform 731.
Each of the top supports 732, for example, may be about 13 to 15 inches
long. The bottom supports 734 may be elongated wooden bars of similar
length to the top supports 732, having a substantially rectangular
cross-section. The bottom supports 734 are pivotably coupled to linkage
systems 720.

[0076] The top of each top support 732 is coupled to the bottom of the top
platform 731. The bottom of each of the top supports 732 is coupled to
the bottom supports 734 via the side bars 733. The side bars 733, for
example, may be wooden rods that connect the top supports 732 to the
bottom supports 734 in a substantially parallel arrangement. Each of the
top supports 732 and the bottom supports 734 may have bores that receive
the side bars 733. Alternative techniques for coupling the side bars 733
to the top support 732 and to the bottom support 734 are also
contemplated, however.

[0077] The central support structure 710 includes a pair of base
structures 711 for locating the ottoman 700 on a floor surface and
providing a steady base for the ottoman 700. Each of the base structures
711 may be an elongated wooden bar having a substantially rectangular
cross section. The base structures 711 are transversely coupled in
parallel by rods 712. The central support structure 710 further includes
center foot bars 713 coupled to, and extending upwardly from, the base
structures 711. The center foot bars 713 are also coupled to top foot
supports 714 of the central support structure 710. The top foot supports
714 may also be transversely coupled in parallel by the rods 712. The top
foot supports 714 are pivotably coupled to the linkage systems 720.

[0078] In addition to providing the gliding mode, the relative arrangement
of the central support structure 710, the linkage systems 720, and the
top structure 730 also provides a nursing mode. In the nursing mode, the
linkage systems 720 allow the top platform 731 to pivot relative to the
central support structure 710 and provide an angled footrest. The angle
of the footrest may be any angle, for example, between 30-60 degrees. The
top portion 730 of the ottoman 700 acts the footrest in both gliding and
nursing modes.

[0079] To lock the ottoman 700 in the nursing mode, the ottoman 700
includes a locking mechanism 740 as illustrated in FIG. 18. For example,
the locking mechanism 740 includes a pin (not shown), a pair of pin
supports 742, and a lever 743. Each of the pin supports 742 is coupled to
the bottom surface of top platform 731. The pin supports 742 are arranged
in parallel such that a pin may extend between pin supports 742.

[0080] Distal ends of a pin may be inserted in bores formed in each of the
pin supports 742 and a central portion of the pin may be inserted through
a bore extending fully through the lever 743. FIG. 19 illustrates an
exemplary lever 743. The lever 743 may be an elongated bar having a
substantially rectangular cross-section. A first end of the lever 743 may
have a bore 751 passing configured to receive the pin such that the lever
743 may pivot about a bearing formed by the pin. The lever 743 may pivot
freely on the pin such that gravity allows the lever 743 to hang and
swing freely as the top structure 730 moves. An engaging structure 752 of
the lever 743 may be configured to engage with one of the rods 712 to
lock the top structure 730 in the nursing mode.

[0081] A user may configure the ottoman 700 from the gliding mode shown in
FIG. 15A to the nursing mode shown in FIG. 15B by applying a force to the
top of the top platform 731 to draw the top structure 730 up and back.
Such action may be achieved by acting on the top of the top platform 731
with one foot or both feet. Because the lever 743 pivots freely on the
pin, the lever 743 may hang due to gravity between the rods 712. As the
user pulls the top structure 730, a surface of the lever 743 may slide
along a surface of a rod 712. Once the user draws the top structure 730 a
certain distance, the engaging structure 752 of the lever 743 engages the
rod 712. By engaging the rod 712, the lever 743 locks the top structure
730 in position, e.g., lock the height and tilt/angle of the top
structure 730, thus providing a stable angled footrest for the user.
According to an aspect of embodiments, a nursing mode for an embodiment
may be easily and intuitively achieved by configuring the ottoman with
one's foot while already seated in a chair. In particular, a user may
safely and easily transform the nursing gliding ottoman from a gliding
mode to a nursing mode while seated in the chair 100 and holding an
infant.

[0082] Conversely, the user may configure the ottoman 700 from the nursing
mode shown in FIG. 15B to the gliding mode shown in FIG. 15A. In
particular, the user may manually disengage the lever 743 from the rod
712 and allow the top structure 730 to move into the horizontal position
for the gliding mode. By requiring a user to disengage manually the lever
743 from the rod 712, the ottoman 100 remains locked in the nursing mode
and will not become accidentally unlocked. Alternatively, the user may
place one or both of his/her feet under the top platform 731 and may
press upward or forward on the lever 743 to disengage the engaging
structure 752 of the lever 743 from the rod 712. Gravity then acts on the
top structure 730 to move the ottoman 700 into the gliding mode.

[0083] While the embodiment may easily be configured between the gliding
mode and the nursing mode by disengaging the lever 743 from the rod 712,
alternative embodiments may include a safety mechanism, for example, a
release control, that requires the user to move from the chair to operate
the ottoman 700. Such a safety mechanism may, for example, prevent a user
from inadvertently placing his/her foot underneath the top platform 731
in the nursing mode and disengaging the lever 743 from the rod 712.
Alternative embodiments may include a plurality of locking mechanisms
configured to lock the top structure 730 in a position relative to the
bottom structure 710.

[0084] FIG. 20 illustrates an alternative exemplary locking mechanism 770
for the ottoman 700. Locking mechanism 770 includes a spring 771
configured to urge a pin 772 into a lock opening 773. A handle 774 may be
fixed to an end of the pin 772 to allow a user to urge the pin 772
against the force of spring 771 to disengage locking mechanism 770.

[0085] While the present invention has been described in connection with a
number of exemplary embodiments, and implementations, the present
inventions are not so limited, but rather cover various modifications,
and equivalent arrangements, which fall within the purview of prospective
claims. For example, although some aspects of the present invention may
be described with reference to separate elements, it is understood that
some elements may be combined to provide an integrated structure while
satisfying the functions of the elements. In addition, although aspects
of the present invention may be described in separate embodiments, it is
contemplated that the features from more than one embodiment described
herein may be combined into a single embodiment. Furthermore, it is also
understood that aspects of the present invention are not limited to the
particular shapes and dimensions described or illustrated in this present
application.
